Pidgins and Creoles do not have a single phonology and phonology remains the least stable system in otherwise stabilized pidgins.

While this research demonstrates that phonological previews aid in the processing of the target word, evidence from individual difference studies suggests that phonology is not used in the same manner by all readers.

While these languages shared phonology and grammar, they had entirely different vocabularies.

phonologist

I'm also oversimplifying, but that's okay, because I'm not a phonologist or a phonetician.

Though more study is needed… I'm a big fan of the scientific method, but this reminds me of a spoof term paper I once wrote, many years ago, after having read one too many phonetics articles debunking the perceptions of phonologists.

I don't know any working phonologists today who think that morphologically-conditioned (or otherwise ‘irregular’) sound patterns are ipso facto distinct in every way from perfectly transparent ones.
